Troubleshooting EAS after SR Upgrades

After performing an SR (System Release) upgrade, verify that your EAS equipment

is still properly configured in the ISDS. Complete all the procedures in Test the EAS

from the ISDS (on page 54).
After completing the procedures, verify that you can generate an EAS message for

the EAC. Refer to Verify Your EAS Equipment Configuration (on page 5) and the

manufacturer's documentation for more information.

Troubleshoot the MMM Server

The MMM Server relays the TXT file to the PassThru process and converts the WAV

file to AIFF format. It then places the AIFF file on the bfsServer. The system logs the

MMM Server activity in MMMServer.[xxx] files, which are located in the

/dvs/dncs/tmp directory.

Increase Debugging on the MMM Server
You can troubleshoot the MMM Server by increasing the debugging process.

CAUTION:

Do not let this increased debugging process run for more than a few hours.

This process uses a large amount of disk space, so use this procedure only

during troubleshooting.

Follow these steps to increase the debugging process on the MMM Server.
1 Open an xterm window on the ISDS.
2 Type cd /export/home/dncs and press Enter. The /export/home/dncs directory

becomes the working directory.

3 Type vi .profile and press Enter. The system opens the .profile file in the vi

editor.

4 Find the line containing export EMCDEBUG= in the file.

Example: export EMCDEBUG=SBbKKQ0-9

5 Does the line contain an L?

Example: export EMCDEBUG=SBbKkQ0-9L



If yes, close the file, you have completed this procedure.



If no, append an uppercase letter “L” to the line and press Enter. The line

should now read similar to the following:
export EMCDEBUG=SBbKkQ0-9L

6 Save the configuration.
7 Stop and restart the MMM Server group to activate the new debugging settings.

For more information, go to Stop and Restart the MMM Server (on page 73).
